Application filed October 29, 1917, fs iia' n f eaooo.

To all whom z'tmay concern."

Be-V it-known that I, BEvILLlV. WHIT- WORTH, a citizen of the United Statesof My invention relates to'improvements in' fastening means for doors, and the object of my improvement is to supply'simple-and convenient means for releasably fastening doorsv to door casings, and which will be particularly applicable to grain doors for cars, my improved fastening means being adjustable to secure doors of difiering widths interchangeably.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a door casing and door, with the door secured to the casing by my improved fastening-means; Fig. 2 is a front elevation, on a magnified scale, of said fastening means as connected to a door jamb; Fig. 3 is an endelevation of the same; Figs. 4 and 5 are perspective views of opposite ends of the slide and attached cam of said fastening means, and Fig. 6 is a perspective view of the socketed base bar of the fastening means.

Similar numerals of reference denote corresponding parts throughout the several views.

The numeral 15 denotes the door casing of any structure, such as a freight-car used for carrying grain.

I have shown a door closure for the door opening of said casing composed of sections 16, 17 and 18, the construction of which is described and claimed in another application for patent now pending.

Ihe door or closure which is formed of said sections, or any other type of door, whether single or sectional overlaps and is secured to the jambs of the door casing 15 by means of my improved fastening means. This fastening means is devised to adjust ably secure doors of different widths to said jambs, as it often happens that grain doors of different widths are found in different cars, in which the interspace of the door casings are not of coincident dimensions.

The numeral 1 denotes a base-bar pro- FASTENING ivrnnlvsnoanoo ts,

Specification of Lettersratent. 191B- fideawah a of spaced rectangular sockets in itsouter faoe',"the sockets'being of like dimensions, and-each having a con cave'inner wall-The door-has at opposite ends of its front-face like horizontal recesses 11 wider invertical dimensions than said bar 1, the bar being secured flush therein by means of screw-bolts 13 passed through orifices 3. The bar'l is trapezoidal in cross-section and upon it is 'sli'dingl'y mounted 'a "slide-body 4 'whose longitudinal "trapezoidal channel or groove 5 fits it upon the bar to prevent its displacement therefrom. The slide-body 4 has oppositely-extending cylindrical pins on its opposite ends, one pin 10 adapted to enter a socket 14 in the door-jamb, the other pin '6 serving as a bearing or support for a cam 8 mounted rotatably thereon, said cam having a handle 9. The cam 8 is of such a form and size as to be received into any of the like sockets 2 in said bar 1 to fit the concavity thereof and to 'frictionally interlock therewith when the, handle 9 is swung downwardly as shown by the full lines in said Fig. 3. When the handle 9 is swung upwardly to the position indicated by the dotted lines in said Fig. 3, it clears said bar 1 permitting the slide-body 4 to be moved longitudinally along the bar in either direction to any position of adjustment therealong. The door is placed to contact with the rear face of the door-casing 15, and the slide-body then moved along the bar 1 to engage the adjacent jamb, as shown in Fig. 2, when the cam may be rocked downwardly to secure it in the underlying socket 2, the pin 10 having been received into the socket 14 of the jamb. The cam is secured on the other pin 6 by means of a split-key 7 or by riveting over the extremity of the pin, or in any other convenient manner.

In practice pairs of such fastening means are employed placed on opposite sides of thedoor to engage the opposite j ambs, as shown in Fig. 1, which firmly locks the door in place against either longitudinal movements or movements at a right angle to the door, without any modifications or additions to the door-casing other than the provision of a few sockets 14 in the jambs which do not Having described my invention, What I claim as new, and desire to secure by Let ters Patent, is

1. In combination, a door-jainb'having a socket, a door having a plurality of l1ke concave alined sockets, a slide-body mount ed adjustably and slidably upon said door to move to and from said jamb socket, said slide-body having a pin movable into sa-id jamb-socket, and] a convex cam mounted to rock upon said slidebody and receivable fittingly and con ipressively into any of said door-sockets when the slide-body is adjusted and locked with said jamb by engagement of its pin with said amb-socket.

2. In combination, a door-jamb having a socket, a door overlapping said jamb and having a grooved seat, a plate secured in said grooved seat flush with the surface of the door to underlie the jamb, said plate having a plurality of like semi-cylindrical sockets, a slide-body slidably mounted on said plate and having-a pin adapted to enter and engage said jainb-socket, and a cam mounted to rock on sald slide-body and adapted to be shifted to engage elther doorsocket to hold the door against longitudinal IDOVGD'LGIHLS or movements at a right angle to the door.

3. In combination, a door-Jamb having a socket, a door having a depressed seat there- BEVILL W. WRIT-WORTH.
